Application tiled January 16, 1892. Serial No. 418,325. (No model.)

To @ZZ whom it may concern: that by this means a barrow-section perfectly Be it known that we, CHARLES ALBERT AN- flexible is formed. DEEsoN, ALEXANDER WrLsHER ENGLAND, 7 designates a weightbar, of which there is and FRANK DAVID ENGLAND, citizens of the a series, the Weight-bars alternating with the 55 5 United States, residing at Pembroke, in the harrow-bars- Each weight-bar is provided at county of Christian and State of Kentucky, its end with a recess 8 and with an L-sha`ped have invented a new and useful Harrow, of metal clip 9, the outer end of which extends Which the following is a specification. down over the end of the bar. The recesses Our invention relates to improvements in thus formed engage the short chain-sections 6o 1o harrows; and the objects in view are to pro- 6 between the barrow-bars. These weightvide a barrow of that class comprising a sebars are plain or untoothed and are simply ries of toothed harroW-bars loosely connected to give Weight to the structure. The front and to so arrange the same as to thoroughly and rear bars 1 are provided at their centers pulverize the soil, to provide a cheap and conwith upwardly-projecting convened or round- 65 t5 venient means for connecting the harrowed bearing-blocks 10,which extend some disbars, for weighting the same, to provide tance above the series of intermediate harmeans for regulating the tension of. the harrow-bars. These blocks support a superimroW as a Whole, and a convenient seat arposed tension-barll,considerablylonger than rangement for supporting the operator or the barrow as a whole, and therefore having 7o zo driver. its ends extending in front and in rear of the Other objects and advantages of the inven` harrow. The ends of the tension-bar are bevtion will appear in the following description, eled or chamfered, as shown, and an inclined and the novel features thereof will be parperforation 12 is formed in each beveled end, ticularly pointed ont in the claims. the perforations being oppositely inclined 75 z5 Referring to the drawings, Figure 1 is a with relation to each other. In each perfoplan of a harrow constructed in accordance ration an inclined threaded bolt 13 is seated, with ourinvention. Fig.2isasideelevation. the lower ends of the bolts terminating in Fig. 3 is a central section. Fig. 4 is a detail eyes 14. Short chains 1 5 connect the eye of in perspective of the ends of two adjacent each bolt with a staple 16, projecting from 8o 3o barrow-bars. Fig. 5 is a detail of the dragthe front face of the adjacent end barrow-bar bar. Fig. 6 is a detail of one of the end cast- 1. Upon the upper or threaded ends of the ings detached. bolts hand-wheels 17 are threaded, so that, as Like numerals of reference indicate like will be obvious, the bolts may be adjusted in parts in al1 the figures of the drawings. the perforations of the tension-bar, and thus 8 5 35 In practicing our invention We employ a the entire series of loosely-connected harrowseries of barrow-bars 1, which in cross-section bars may have their tension increased or diare rectangular or square, and each bar is minished, as may be found desirable. The provided With a series of depending harrowcross-cleats 18 are pivoted at their ends to opteeth 2, those of each bar alternating with reposite parallel longitudinally-disposed beams 9e 4o gard to those of the adjacent bars, so thatall 19, such cross-cleats being located adjacent to portions of the surface over which the harrow and at the inner sides of the convexed bearis dragged are thoroughly pulverized. Over ing-blocks 10 and under the tension-bar 11. each end of each bar 1 there is fitted a cast- The beams 19 rest upon a series of small conmetal rectangular frame 3, two of the diagovexed bearing-blocks 20, with which each har- 9 5 45 nelly-opposite corners of which are provided row-bar 1 is provided at each side of its cenwith perforated lugs 4:. Two of the edges of ter. Short seat-bars 2l are pivoted, as at 22, the frame have flanges 5, which are inwardly to the centers of the beams 19, and from the disposed and embrace and are bolted to the opends of the said seat-bars rise seat-standards positesides orfaces ot the barrow-bars. Short 23, which at their intersection have pivoted roo 5o chain-sections 6 serve to connect the adjacent thereto, as at 24, a driver-seat 25. At the inperforated lugs of each pair of castings, so ner sides of the rear barl eyes 2G are located,

and these eyes are for the accommodation of Vand removable engagement with a pair of hooks 27, which extend from the upper edge of a drag-bar 28, designed to drag after the harroW, and thus smooth to a nicety` the soil which the teeth of the harrow have pulverized.

From the foregoing description, in connection with the accompanying drawings, it will be seen that We have provided a harrow of great simplicity, strength, and durability, one in which the several bars may be readily adj usted so as to place the same under greater or less tension, have provided means for adj usting the weight of the harroW in accordance with the soil and the desired depth of penetration, and finally have provided an improved seat-support whereby the switchings or lateral movements of the harroW are not communicated to the seat, but the latter permitted to maintain its alignment With the draft.

The Weight-bars, as before stated, are removable from the hai-row, and when in position may be temporarily secured by means of pins 29, passed through perforations 30,

series of barrow-bars iiexibly connected, of 1 the tension-bar extending beyond the front l and rear ends of the harrow and provided with openings, screw-eyes mounted in the .Y

openings, hand-Wheels mounted on the screws, and short chains connecting the eyes With the front and rear bars of the harrow, sub stantially as specied.

3. In a harrow, the combination, with the series of transverse barrow-bars iiexibly connected, the end bars being provided with conveXed bearing-blocks, ot the tension-bar projecting beyond the front and rear harrowbars and having its ends provided with inclined perforations, threaded eyebolts located in the perforations, hand-wheels mounted on the eyebolts, and short chains connecting the lower ends of the eyebolts with the front and rear harrow-bars, substantially'as specitied.

4t. In a harroW of the class described, the combination, with the series of harroW-bars iiexibly connected, the front and rear bars being provided with the central blocks and each bar being provided at each side of its center with a convex-ed bearing-block 20, of the longitudinal parallel beams 19, located upon the blocks 20 and at each side of the central blocks, the cleats 18, pivotally connecting the beams 19, the seat-bars pivoted on the beams, the standards secured to the ends of the seat-bars, and the seat mounted upon the standard, substantially as specified.

5. In a harroW of the class described, the combination, with the series of harroW-bars, of the series of metal frames embracing the ends of the bars, each frame being provided with inwardly-disposed bar-embracing anges bolted to position and provided at opposite sides with perforated ears, and short chains connect-ing. each adjacent pair of ears, substantially as specified.Y Y

In testimony that We claim the foregoing as our own We have hereto aiixed our signatures 1n the presence of two Witnesses.
